multisite - White pages on sub domains after server transfer

admin管理员组

文章数量:1416051

I recently just moved servers with a multisite install and kept the same domain.

I can access all the backend features and logins for each subdomain but when trying to visit each subdomain site, it just loads a blank white page.

I have setup wildcard subdomains in cpanel and checked the wp options and wp config.

Has anyone else ever had this issue when migrating servers?

• White blank pages normally indicate a PHP Fatal error has occurred, but the error isn't being displayed on the frontend. Can you look through your error logs and find the error message? – Tom J Nowell ♦ Commented Aug 7, 2014 at 18:48
• I have not been able to find or setup error logs yet. I just find it strange that only the subdomains on the account are getting the white screen and the entire backend works fine. I don't see anything wrong with the theme files either. – user3630457 Commented Aug 7, 2014 at 19:02
• Ah without knowing what the error is there's not a lot that can be done to help – Tom J Nowell ♦ Commented Aug 7, 2014 at 19:03
• Parse error: syntax error, unexpected '[', expecting ',' or ';' in /home/radiobra/public_html/wp-content/themes/radioresponsive/index.php on line 15 – user3630457 Commented Aug 7, 2014 at 19:34
• I checked the theme file and it looks fine. – user3630457 Commented Aug 7, 2014 at 19:35

Your comments state that the line in question that gives the fatal error causing your white pages is this line:

<div id="whatstrending"><h1><?php echo get_option('radio_options')['blog-header'];?></h1></div>

Most notably:

get_option('radio_options')['blog-header'];

Or more specifically:

functioncall()[]

This is invalid PHP up until recently, and your new host doesn't run a version of PHP that supports this.

You can fix it by refactoring it from:

echo get_option('radio_options')['blog-header'];

to:

$options = get_option('radio_options');
echo $options['blog-header'];

Rinse repeat in any other situation that follows the same pattern. As a sidenote, the function()['arrayaccess'] pattern is an anti-pattern, a single line should do a single thing, and calling a function then accessing its return value is 2 things. Not to mention that it will fail if the function doesn't return an array.
